Immigrants without Proper Authorization: Immigrants without proper authorization to be in the country must still pay taxes on their worldwide income and all state and local and federal sales, property, gas, excise and other taxes. It is estimated that they pay in roughly $12 billion into Social Security and Medicare taxes annually as well as another $12 billion in state and local taxes. And they are not eligible for Social Security retirement benefits, Medicare, child tax credit, earned income tax credit, or the premium tax credit.
